Oh where to start?
Little Kitty is quite adept at hunting, despite a noisy bell on her collar. I think she moves at supersonic speeds...
There was a little bird recently that fell prey to her. She batted it about the patio for a while and we thought, 'well, it's dead, and she's well fed, so let her play with it, praise her and then we'll dispose of the poor bird'... ten minutes later we look out to see she's disappeared and all that's left is an unidentifiable portion of bird. I seriously could not tell what part it was. DH was tasked with dispatching the remains.
Her other party trick is blue bottles/flies. She catches them and traps them under her paw, letting them out after a few seconds and catching them again and again. Sometimes she carries them in her mouth and puts them on the floor to play with them this way. Then you hear "crunch, crunch, crunch" when she tires of playing and a happy purring as she licks her lips and wanders off.
Our old cat, Jess, RIP, once punished us for leaving her alone for a long weekend. She had food, water and a safe place to sleep. But it was longer than normal so she decided to punish us for the same number of days she was alone... Every morning we came down to small amounts of cat pee at two foot intervals around the skirting boards of the kitchen.
Non-cat related, we were on holidays for a week, height of summer, and I forgot to empty the kitchen garbage bin... came home to what looked like tiny pieces of rice all over the kitchen... I still shudder and gag thinking about it and having the clean up all those maggots and baby flies.
I don't have a problem with getting blood taken, I've great veins and tolerance for pain. But my DH almost faints at the sight of blood and cannot bear even the mention of a needle. I was relaying this to a nurse one time while she was getting a blood sample and just as she was taking out the needle this huge spurt of blood comes out, just missing her. Relished telling DH that just to see his reaction - EvilIrishKitty.
